A vehicle door attachment unit for rotatably and detachably coupling a vehicle door to a vehicle body. The unit may include a bodyside bracket mountable to the vehicle body and having first and second portions with respective first and second apertures, with the first and second portions extending generally away from the vehicle body. A doorside bracket may be mountable to the vehicle door and include a segment with a third aperture, the segment extending generally away from the vehicle door. A retaining mechanism may extend through the third aperture, and through the first and/or second apertures. A fastener may extend through at least one of the apertures and mate with the retaining mechanism to substantially align the first, second, and third apertures. A bearing may be disposed on the retaining mechanism for providing rotational freedom between the retaining mechanism, and the bodyside or doorside bracket.
